Definitions

  • the invention relates to an effective against increased tendency to eat protected screw and a method of manufacture a protective layer on a screw.
  • the uncoated Thread of the screws treated with lubricant, e.g. with one composed of oil, thickener and solid lubricants Lubricant.
  • Lubricant e.g. with one composed of oil, thickener and solid lubricants Lubricant.
  • Lubricant By using this lubricant becomes the friction between the screw and the thread reduced.
  • the oil components evaporate in one Increasing the temperature, leading to a diminishing lubricating effect leads to eating again when loosened again the screw connection can lead.
  • Screw, flange and plug connections for high temperature applications which are not lubricated are subject to increased Levels of oxidation, which ultimately leads to seizure which contributes screw, flange and plug connections.
  • the use of oils can also meet the usual requirements not satisfactorily fulfill the screw connections, since oils tend to dry out and burn and thus also with them the risk of drying out with subsequent Wear on the thread surface when loosening again consists.
  • the preparation of the solution containing an aluminum Material generally contains 50 parts by volume of the Dilution solvent, based on 100 parts by volume of this Solution added.
  • This dilution solvent that is added to or contained in the solution evaporates in the air of the workplace and the operator harm if she inhales these vapors.
  • Document DE 40 05 502 A1 describes a process for the production described a protective layer on a screw. It contains a solvent, water and an aluminum Funds mixed in a first container to make a to obtain electrolytic solution.
  • a second container a variety of screws are inserted. The second container is placed in the first container so that the Screws are immersed in the electrolytic solution. This creates a layer of aluminum on each Screw through electrolysis. The second container is during the electrolysis swung. Then the screws washed with water to remove the solvent residues attached to the Stick screws to remove.
  • the object of the present invention is to provide a screw connection, which has a screw and a counter thread, which has a low tendency to eat and a Process for the production of a protective layer on a Provide screw or on a counter thread.
  • the task aimed at the screw connection is solved by a screw with an aluminum-containing high-temperature paint on the thread.
  • the task aimed at the screw connection also becomes loosened by a counter thread on which an aluminum-containing High temperature paint is applied.
  • the lower part of the Thread coated with the aluminum-containing high temperature paint In an advantageous embodiment, the lower part of the Thread coated with the aluminum-containing high temperature paint.
  • the area of the screw or of the thread with a protective layer, which in the application is particularly burdened.
  • the object directed at the method is achieved by by applying an aluminum-containing high-temperature paint to the Screw applied and then hardened and baked becomes.
  • the advantage of this solution is in particular in that the process is very easy to use.
  • the process does not require any special security measures, so it's also on a construction site during a revision, Repair or commissioning can be applied.
  • the aluminum-containing High temperature varnish applied at room temperature.
  • the aluminum-containing High temperature paint applied in two thin layers. This creates the advantage that the tendency to eat the screw through a second layer of aluminum High temperature paint is reduced.
  • the thread after baking in the aluminum-containing high-temperature paint lubricated with a lubricant is also avoided.
  • the coated screws can be used in turbomachinery become.
  • the coated screws be used in steam turbines or in gas turbines.
  • Figure 1 is the longitudinal section of a coated screw 1 to see.
  • the screw 1 has a head 2 and along the Longitudinal axis 3 has a thread 4.
  • the thread 4 extends in this embodiment from head 2 to the beginning of the screw 6.
  • the screw 1 has an upper part 7 and a lower part 8 along the longitudinal axis 3, the Separation between upper 7 and lower 8 part of screw 1 is variable.
  • Other embodiments of the screw 1, such as e.g. one only partially applied in the longitudinal axis 3 Thread 4, can be used.
  • the screws can e.g. out 12% chrome steel.
  • the screw 1 can be used in steam turbines or Gas turbine construction are used.
  • the screw 1 is with an aluminum-containing high temperature paint 5 provided on the entire thread 4.
  • the aluminum one High temperature paint does not have to be on the entire thread 4 are applied, for some applications it is sufficient lower part 8 of the thread with the aluminum-containing high temperature paint 5 to be provided.
  • the screw 1 can high-alloy materials exist.
  • the aluminum-containing high temperature paint 5 can be applied to the counter thread become. The desired advantage of a lower tendency to eat is still given.
  • the procedure is simple to use.
  • An aluminum one High temperature paint is at room temperature in two applied thin layers.
  • the aluminum-containing high temperature paint can be a commercially available aluminum-containing high-temperature paint his. Applying the two thin layers happens in succession with a time offset. The two thin layers are then dried and cured. Drying and curing can take place under Air atmosphere. Then the aluminum-containing High temperature paint can be baked. The baking temperatures can be between 160 ° C - 750 ° C.
  • the thread 4 is additional lubricated. A commercially available lubricant is used for this used. The tendency of the screws to seize is caused by this Process significantly reduced. Reduced by this The tendency of the screws to seize can save considerable costs become.
